A no more paper cuts
B no time wasted turning pages, a flick of a finger and I'm on the new page.
C no cramped hands holding pages open on a new book
D no dust, mildew or mold
E no pages stuck together, or miscut at the publishers.
F No stains, glops, chocolate smears, or otherwise illegible words.
G no missing pages
H no covers falling apart, pages slipping out.
I no getting up to go search for a new book when I finish one.
j no lugging a backpack around if I am going to be gone for a few days.
my E-reader has an estimated years supply of reading, all near instantly accessable.

Just read as fast as my eyes can read and my finger can caress the page turn button.
Its bloody awesome! I enjoy reading much more than I used to, not less.

I second your list. If I may add:

K - For someone who moves frequently, no more hiring trucks only to move my books around. No more paying for storage (I have done this, couldn't part with my collection - ended up donating it to the local library in the end). No more paying excess luggage fees just because I need to have 10 books with me.
